SPECIFICATION forming part of Letters Patent No. 658,988. dated October2, 1900.

Application filed April 14, 1900. serial Ila-12,930. (No specimens.)

- To all whom it may concern.-

Beit known that. I, JOHN A; JUST, of Syracuse, in the county of Onondagaand State of New York, have invented newjand useful Im- 5 provetnents inSolidified Mineral-0il Distillates and Methods of Making the Same, of Vwhich the following is a full, clear, and exact description. v

My invention relates to the solidification of mineral-oil distillates;and it consists of a new process and-product.

I change mineral-oil distillates from their usual liquid state to astate of permanent jelly-like solidity by incorporating them with asolution of casein and 'soap. To such asolution I'orefer to addglycerin, as glycerin incorporated with the product enables'it better towithstand the breaking-down tendency of low temperatures, and it rendersthe casein more soluble and transparent. 4

Generally stated, my process is as follows: I add to a given quantity ofa solution of casein, soap, glycerin, and water a somewhat less quantityof mineral-oil distillate and thoroughly agitate the mixture until itunites and forms a uniform emulsion. Then I gradually add moredistillate and incorporate it with the emulsion-like mass by agitation.The mass becomes thicker asadditionaldistillate is incorporated andfinally acquires a stilt jelly-like consistency.

In carrying out my process I first prepare a solution consisting ofabout four parts, by weight, of desiccated caseinate, such as suitablesodium caseinate, in about seventy parts of water, towhich'I add aboutone to three parts of soap and about nine parts of glycerin. Thissolution may be made by adding the glycerin to the water andthendissolving the.

caseinate in .it. Heating the mixture ona water-bath will facilitate thecomplete solution of the casein. Then the soap may be added anddissolved. The parts are to be estimated by weight. The caseiuate issoluble in water. I pour this solution, preferably when it is hot, intoa suitable vessel containing, say, thirty parts of mineral-oildistillatesuch as petroleum, ether, or naphtha-at ordinary temperatu reand thoroughly shake the It soon emulsifies, becoming uniform inappearance and showing a tendency ing capacity of the solution isexhausted/6o Then the mass will have reached a solid jellylike form.

"The solution described will solidify about twenty times its weight ofthe lighter distillates, such as naphtha or benzene.

In carrying out the process care should be taken that each addition ofdistillate is thoroughly incorporated with the mass before anotheraddition is made and too large a quantily of distillate should not bea'd'ded at one time. than is readily absorbed by continued shaking, themass should be allowed to rest and part of the distillate poured 0E.Renewed shaking will then bring about a solidification or thickening,and the liquid withdrawn may be readded and incorporated.

Ifdesired, less water than the amount specified may be used at the startand more water. added later. A small quantity of water added at anystage of the process often facilitates the incorporation.

As stated, a solidification may be efiected by the solution of caseinand soap without the addition 0t glycerin, but glycerin improves theproduct.

A desiccated caseinate is specified herein, as it is a desirable form ofcasein from which to. make a solution, and definite quantities of it canbe indicated; but an equivalent solution may be made direct fromm-ilk-ourd in 'ways well known, if desired.

A good tallow soap is suitable for the solution, but other soap may beused.

Mineral-oil distillates (or mixtures of such distillates) may besolidified in the manner described, and thus made available for newuses. In their changed form they give off their vapors but slowly andare practically non-explosive. They emulsify readilyin cold water andmay be used with advantage in washing clothes and other fabrics, and

leaving, as they do, but a very light and harmless residue, which issoluble in Water and easily removed by sponging, they may be safely usedin cleaning clothes. The benzene or other distillate in this jelly-likeform may be applied to the garment to be cleansed by a sponge or rag andwhen dried brushed off or sponge-d off, as aforesaid.

It is known. that mineral-oil distillat'es can be solidified by beingiucorporated with a solution of soapybut such solidifications are notstable or permanent. They readily break down and go back into liquidform and are of'no practical value. This is due to the insufli'cientstrength of the structure built up by the process in question, and theessence of my invention liesin theincorporatinn with the emulsifyingsolution of a structure-pre- For practicalpurposes this material must beinsoluble in mineraloil distill-ates and must dissolve in water atordinary temperatures to form a tenacious or There exists a number ofmaterials answering this description which produce more or lesspermanency of jelly structure; but of all these I prefer a soluble casehate, as above described, since this substance produces a jelly stablein extreme cold and which improves with age,

I em ploy soap in connection with casein, as described, and produce astable and permanentsolidification. Casein and caseinate are insolublein mineral-oil distillates,and it gives their solidifications necessarystrength and firmness.

They will not melt and spread when ignited,

- but will burn.

Having thus fully described my invention, what I claim, and desire toprotect by Letters Patent, is

1. A composition of matter consisting of a mineral-oil distillate,thickened or solidified by an aqueous solution of soap and a sub stanceinsoluble in said distillate and forming with water at ordinarytemperatures a tenacious or viscid solution.

2. The herein-described composition of mineral-oil distillate audasolution of acaseinate and soap in water.

3. The herein-described composition consisting of a mineral-oildistillate and a solusuch liquids by agitation with a solution-of acaseinate, soap and glycerin in water.

6. The process of solidifying mineral-oil distillates which consists inemulsifying such distillates by shaking a quantity thereof with asuitable quantity of a solution of a caseinate'and soap'in water, and inthen gi'adually adding and incorporating more of such distillates byagitation.
